Specification forming part of Letters Patent No. 125,661, dated April16, 1872.

SPECIFICATION.

I, WILLIAM T. CARROLL, of Woonsocket, in the county of Providence andState of Rhode Island, have invented certain Improvements in Stands forSpinning-Frames, of which the following is a specification:

Figure 1, in the drawing, is a front view of one section of my improvedroller-stand, with the mechanical devices operating the same, and Fig. 2is a top view of the same.

The present invention relates to a certain new and useful meansforadjusting and operating roller-stands connected with spinningframes,self-operatin g mules, roving machinery, &c., the object of which is tofurnish an expeditious and effective means of adjusting the back andmiddle rolls of the spinning-frame, 850., so as to adapt them to cottonof anylength of staple, .as well as to improve the yarn spun .fromcotton of different lengths of staple. My improvement consists of aseries of mechanical devices, to be fully explained in due course, soarranged and operated as to allow the several roller-stands connectedwith a spinning-machine to be instantly adjusted by one and the sameoperation while the machine is in motion, instead of, as heretofore,requiring the time and labor of two men for several'hours, and

delaying the action of the machinery while the adjustment of theroller-stand is proceeding.

In the drawing, b is one of several rollerstands, which are arranged inpairs in opposite parallel rows at a short distance from each other, ona roller-beam of a spinning or other like machine, and is formed with abearing, '5, for holding the front roll. Traveling longitudinallybackward and forward in a slot formed in the upper portion of the standb is a sliding frame or stand, a, provided with bearings lm that holdthe back and middle rolls, and has formed on its bottom a lug, h, inwhich works the screwend of a shaft, d, formed with a thread on eachend, and connecting each pair of roller-stands b. Attached to the shaftd, which is supported by a frame, 0, is a worm-gear, e, that engageswith a worm, f, which is formed on a shaft, 9, that extends the wholelength of the spinningframe, and connects with the several pairs ofroller-stands b, and which is operated by a wheel, crank, or any othersuitable device.

The operation of my improvement is as follows: By operating the wheel orcrank, &c., the shaft g is revolved, thereby causing the worm f toactuate the wormgear 6 which rotates the shaft d, the screw-ends ofwhich, working in the lug h, operate the sliding frame either forward orbackward on the stand 11, according to the direction in which the wheel,&c., is turned. By the above operation the distance between the frontand middle and back I rolls is either increased or diminished, and theadjustment of the rolls is performed at all the stands a by oneoperation. For it will readily be seen that, by the operation of theshaft g, which connects with all the stands a, and actuates the shaft dwhich connects each pair, each and every stand a is at once adjustedwith very little time and labor; and as the machinery, by the presentarrangement, has not to be stopped to allow of the taking apart andreadjustment of the parts, as has heretofore been necessary, avery greatsaving is made in time and labor; and economy is gained in the cost ofmanufacture, as well as securing the production of a better material.For it is well known to cotton manufacturers that, when it is desired touse a grade of cotton with a staple of different length than that theyhave been employing, they must either adjust their rollers to suit thestaple of cotton, or spin it as it is without regard to the adjustmentof the rollers, thereby producing poor yarn. Often the latter course isadopted, owing to the trouble and time required to adjust the rollers bythe ordinary methods in use; whereas, by the adoption of my improvedmechanism, one man can adjust one hundred machines in less time than twomen could arrange one machine by the method heretofore in use; thusobviating the objections above stated.

My adjusting mechanism can be so arranged as to operate the frontroll,instead of the back and middle rolls.

- Having thus fully described my invention, what I claim, and desire tohave secured to me by Letters Patent, is-- '1. The adjustable slidingframe or stand a, formed with lug h and bearings Mn, and arranged so asto travel longitudinally on the stand I), and operated by shaft g,worm-gear e, worm f, shaft d, or their mechanical cquiva lents,substantially as specified.
